Now that the UEB tables are in the liblouis svn we can test both translation and back-translation. The best tool for this is lou_allround, which is available if you have built liblouis on Linux or Mac. It is completely interactive. After you give it a table name you can type r for run and then type in anything you want. It will show both the translation and back-translation and will even tell you if the back-translation matches the original by displaying the message "perfect roundtrip!" If there is sufficient demand this facility can be made available on Windows through a BrailleBlaster subcommand. John -- John J.
